    What You'll Learn:

    By the end of this training, you will be able to:

    • Recognize the concept of the "lost generation" of Autistic adults and describe how masking and socio-cultural factors have contributed to under-diagnosis.
    • Identify common co-occurring conditions (such as ADHD, OCD, PTSD, eating disorders) and understand how autism may be overshadowed in complex cases.
    • Apply the DSM-5-TR diagnostic criteria with more nuance, particularly for adults with non-stereotypical presentations.
    • Incorporate effective autism screening tools into clinical intake processes and feel more confident recognizing autism as part of a treatment course.
    • Understand the high stakes of misdiagnosis — including increased suicide risk, substance use, and treatment-resistant depression — and the protective power of identity integration and community.

    This Training Is Ideal For…

    • Psychologists, therapists, and social workers in private practice or agency settings
    • Clinicians working with adults navigating complex clinical presentations
    • Professionals seeking a more neurodiversity-affirming, identity-centered approach to care
    • Anyone who has ever wondered if they may be missing the full picture in therapy
